An educational interactive program to illustrate equipotential numerical solution procedures

An interactive and graphical computer program implemented in a personal computer environment is discussed. It is designed to allow students to conveniently study the electrical equipotential lines of various types of geometries found in high-voltage installations. The program uses an interactive, graphical user interface to allow students to draw the geometries to be studied directly on the display; the same display is then used to provide a visual output for the equipotential lines as computed by the program. The numerical solution procedures implemented in the program as well as the user interfaces are reviewed. A computational example is discussed along with the required hardware and software environments.
